Following an on-track incident on Lap 57, Verizon IndyCar Series driver James Hinchcliffe was evaluated at the IU Health Infield Medical Center and transported by ground to IU Health Methodist Hospital in Indianapolis.

Hinchcliffe was discharged from the hospital after being evaluated and having a CT scan of his head and neck. INDYCAR Medical Director Dr. Michael Olinger said Hinchcliffe was diagnosed with a concussion. The driver of the No. 27 United Fiber & Data car for Andretti Autosport will be re-evaluated by Olinger and INDYCAR medical consultants before being cleared to drive.

In the occurrence that Hinchcliffe is not medically cleared to continue his driving duties for the Indianapolis Mile Race, E.J. Viso will fill in. Viso competed for Andretti Autosport in 2013. Practice for the 500 Mile Race opens May 11, with qualifications May 17-18. The race is May 25.

“I want to thank all the fans for their messages of concern and support," said Hinchcliffe, who pitted under caution on Lap 54. "I’m a little stiff and sore and I’d love to be back in the car tomorrow, but I suppose I should probably let the doctors make that decision. Such a bummer for the UFD car when things were really starting to come together."

Viso, 29, of Venezuela, finished 13th in the 2013 standings despite not competing in the finale because of illness. He recorded two top-five finishes, with a best of fifth at Toronto 2, and had seven top-10 finishes overall. He was running at the finish in 16 of the 18 races he competed in.

"I don't feel too behind with the other drivers with it being the first oval and being in very good circumstances with the team I was at last year," Viso said. "I know the system and trust their set-ups and trust the feedback of the teammates and trust the car. It's a good scenario. On the other side, I'm covering a good friend of mine, Hinch, and he's going to be back very soon, but in the meantime I'm going to be shaking down his car until he comes back."
